[PATCH v4 20/23] test: mbr: Unmap the buffers after use

[Simon Glass]

This tests maps some local variables into sandbox's address space. Make
sure to unmap them afterwards.

Note that the normal approach with sandbox is to use a fixed memory
address in the RAM, to avoid needing to create a map for transient local
variables.
